Nandina – Pruning
Q: Is it safe to prune my nandina now? I don’t want to affect the berries later this year.
A: March is the very best time to prune common nandina. Cut a third of the canes at 12 inches high, a third at 24 inches and the remaining third at 36 inches. The stems will sprout new foliage in spring. The nandina will flower in late summer, giving you red berries in late fall.
